Priyanka Chopra`s husband and pop star Nick Jonas performed his headbanger number `Jealous` in a white tuxedo jacket at the annual HIV-AIDS charity dinner at Cannes, getting the global A-list invitees up on their feet after dinner was served late on Thursday night, reports `Variety`. "I had the pleasure of playing [the Four Seasons frontman] Frankie Valli in a movie coming out later this year called `Jersey Boys`," Jonas said, before crooning the Valli ballad `Can`t Take My Eyes Off You`.

Nick, who was rocking out on a guitar, was joined by his brother Joe, who serenaded Cannes with `Cake by the Ocean` -- the smash 2015 pop song from his band DNCE. Before the Jonas Brothers performed, Cher, despite her 78 years, belted out one hit number after another for 15 minutes, dressed in a dazzling sequined purple pantsuit, from her own `Believe` to an acoustic rendition of `Walking in Memphis`, Marc Cohn`s ballad that she had covered on her 1995 album `It’s a Man’s World`, `Variety` adds.
